Android & Eclispe - Export Signed application no longer works

All of a sudden I cannot export a signed application in eclipse

Right Click -> Android Tools -> Export Signed Application Package

Nothing happens, I can still install it on the emulator and export an Unsigned package

What is going wrong?

I get the following in the error log when I press the "Export Signed Application Package" menu item

I had the same problem but I dont remember exactly how I solved it... Try refresh the project then Project > Clean and restart Eclipse.

I fixed it, there was another project called MainMenuActivity (I don't know where this came from), it contained not files whatsoever. I deleted this project and now everything works.
